Total eclipse of the sun

This morning, our country have taken place in this century, the longest total solar eclipse, total eclipse zone started from the Yunnan-Tibet, the Trans-densely populated Yangtze River basin. It is understood that our country can be observed in the longest total eclipse of 6 minutes 1 second, is the longest of this century, a total solar eclipse.

Today, 8:01, Tibet wrong county total solar eclipse that began in early loss.

Tibet’s wrong when the County experienced a total solar eclipse, the sky quickly down the dark, the temperature has dropped, the clouds are still thick at the scene, total solar eclipse can not be observed. Total solar eclipse at 10:07:50 rehabilitation round, the local clouds have begun to disperse.

Sichuan, Jiangsu, short-term total solar eclipse can be observed, Shanghai is more than heavy rain, clouds, during the total solar eclipse occurred as the city late at night, but not observed, Hubei, Anhui, Zhejiang, Chongqing and other places to the total solar eclipse can be observed.

Purple Mountain Observatory, Chinese Academy of Sciences Fellow, JI Hai-sheng, the start of the total solar eclipse in India, the first total solar eclipse is seen Campbell Bay, India. From the Indian border into China, from Zhejiang and Shanghai into the Pacific. In the Pacific, the eclipse with the sweep of the Ryukyu Islands, and has been extended to the North West Pacific Cook Islands, where the sun and down with food.

According to the astronomers estimated that such a long total eclipse of the solar eclipse took place only about 6% probability. 22 after the total solar eclipse in 2132 have to wait until time to eat more than see the total eclipse.

Software about security

File encryption

At present, many folder encryption software, there is a major flaw: after encryption it will create a directory in the same encrypted file, and the encrypted files usually have a lock icon. This is equivalent to notice someone else on your computer in the possession of private or important documents, which allow others to try to get the document, such as through the peep password, or violence.

IceSword

IceSword is a sharp knife cut off the back hands. It is suitable for Windows 2000/XP/2003/Vista operating systems, used to identify system behind (the back door Trojan horse) and to handle it, of course, it requires users to use some knowledge of the operating system.

 

IceSword internal function is very powerful. You also may be use a lot of similar software, such as the number of process tools, tool ports, but now the back door of the system-level functions are getting stronger and stronger, the general process, port, registry, file information can be easily hidden, the general tools simply can not find these “behind hands”.  IceSword use a large number of new core technologies, so that these back-door to hide  nothing.

        TianDun perfect encryption software solves this problem is the folder protection software all in the most hidden folder protection tool. Folder after it is encrypted and will not have any in the original directory of encrypted files and folders will disappear from your computer, without leaving any traces of that. Naturally, people have no way of knowing your computer and possession of secret documents, but would not have thought from your computer to obtain information.

FinalData

if you delete a file in the Windows operating system environment, actually only the directory information from the FAT or MFT (NTFS) will be deleted. This means that the file data still remains in your disk. Therefore, from the view of the technical point, this document can be restored. FinalData is just use this mechanism to restore the lost data, even after emptying the recycle bin. In addition, FinalData can be easily recoverd from the formatted file and damaged documents by viruses. Even in extreme cases, if the directory structure have been damaged, it also can be recoveried, as long as the data is still stored on the hard drive.

A interesting lesson: Treasure Hunt

 

Teacher give us three pictures which look the same. If you look it carefully, you can find that the three pictures are difficult size. Why? It’s at the beginning of treasure hunt.

  At first, we know we can get something hidden in the pictures by use the software “OpenStego”. Yes, we get two files named “RANDOM”. We get a clue after opening the pdf file. That is “Secret word number 1 is pirate. Clue for next secret: you found that files can be hidden in graphics. You also realize that the name of a file is arbitrary. You can rename any file to any name and extension. There are two files you should have found named “RANDOM”. One is PDF or ‘portable Document Format’ (this file) and the other is a TrueCrypt Volume. The password for this TrueCrypt volume is ‘thisissecret’.” According to the clue, we can use software “TrueCrypt” open the other “RANDOM”. We do this and get the n  Secret word number 2 is steganography.

Clue for next secret:The truecrypt volume RANDOM where you found this file also has a hidden volume.  Open RANDOM with the password “thisisveryverysecret”. Then we use difficult password to decrypt “RANDOM” and get the next clue: Secret word number 3 is encryption. Clue for next secret: You found secret word number 1 in a file named RANDOM that was really a PDF file. This PDF file contains the last secret word hidden using the program wbStego4 and the password “lastsecret”.  This hidden file is a very small text file that only contains one word.  This one word is secret word number 4. Then we use wbStego4 open the PDF file and get the last keyword “ciphertext”.

  We were happy when we had got the last keyword.　It’s a interesting lesson and I like it.

My girlfriend

My girlfriend is my classmates of high school .Our love is flexuous.

when I was in high school I don’t like her. My deskmate loved her, so he usually invited her to do something and asked me together . Gradually, I found that she is a tender girl and I make a good impression on her. One day I found I love her. But I can’t show my love to her because my deskmate love. It maybe make him sorrow. We just keep in touch with each other in the following years. One day we both on line. We talk into deep night. And I know she didn’t like my deskmate. So I take heart of grace to express my love. To my surprise, she love me too. She said she was glad to become my girlfriend. We fall in love with each other quickly and I found that I loved he than before since I got to know her. In a word, she is my true love and I love her so much.

Trusted Platform Module

The Trusted Platform Module offers facilities for the secure generation of cryptographic keys, and limitation of their use, in addition to a hardware pseudo-random number generator. It also includes capabilities such as remote attestation and sealed storage. “Remote attestation” creates a nearly unforgeable hash key summary of the hardware and software configuration. The extent of the summary of the software is decided by the program encrypting the data. This allows a third party to verify that the software has not been changed. “Sealing” encrypts data in such a way that it may be decrypted only if the TPM releases the associated decryption key, which it only does for software that can provide the same password that was supplied when software “ownership” of the TPM was initially configured”Binding” encrypts data using the TPM endorsement key, a unique RSA key burned into the chip during its production, or another trusted key descended from it.

 A Trusted Platform Module can be used to authenticate hardware devices. Since each TPM chip has a unique and secret RSA key burned in as it is produced, it is capable of performing platform authentication. For example, it can be used to verify that a system seeking access is the expected system.

 Generally, pushing the security down to the hardware level in conjunction with software provides more protection than a software-only solution that is more easily compromised by an attacker. However even where a TPM is used, a key is still vulnerable while a software application that has obtained it from the TPM is using it to perform encryption/decryption operations, as has been illustrated in the case of a cold boot attack.

Travel to Chongqing

 

Chongqing is a well-known city with a history of more than 3000 years. It is the famous historical and cultural city in China. Chongqing is the birthplace of the Bayu Culture. At present, Chongqing is a municipality directly under the Central Government with the largest area, the most administrative districts and the largest population. The original area of the whole city is 82,000 square kilometers, governing former Chongqing, Wanxian, Fuling cities as well as 43 districts, cities and counties in the Qianjiang Region. Chongqing has a population of 30,020,000, most of them are of Han nationality. 49 other ethnic minorities, such as Tujia, Miao, Hui, Man, and Yi also live here but retain their own traditional customs. The colorful local customs have already become an important tourist attraction in Chongqing.

Chongqing has many attractions: cityscapes, mountains, revolutionary sites, cultural relics, parks, scenic spots, and natural beauty. The city offers a variety of choices for the visitor: from meetings and exhibitions, to sightseeing, shopping, dining and entertainment. Chongqing is variously known as “foggy city”, “mountain city”, and “furnace city”. The central urban area of Chongqing is wedged between the Yangtze River and the Jialingjiang River, surrounded by hills and mountains. With green hills and clear waters, the scenery is unique. Buildings are massed in picturesque disorder near the mountains and at the rivers’ edge. From a vantage point at night, one can see a myriad of glittering lights, contrasting pleasantly with clear glistening lights from the waves of two rivers and flashing stars all over the sky. This combination makes for a magnificent scene. 

YuHua Cave

Yuhua cave is located in JiangLe south-easterly direction, is a karst landscape, was formed in 200 million years ago. The tour began in the early Han Dynasty History, Song, Ming has the world famous, as “the first hole Min Shan” and “Mountain of Pearl” is called.

Yuhua cave is a large room of the house of the joint channel-type cavities in the east to the north entrance. Southwest direction toward the hole, and the hole is about 10 kilometers total.Winding the main tunnel, 634 meters long, was development of north-south direction, east-west width 5 — 3O meters, the high of the cave is 10 — 6O meters. Yuhua cave is developed into five levels, each level connected, have been opened up some holes and only one half of the whole can be divided into three channels and six branch hole. Chemical sediments in this hole to become the most important tourist spots and an integral part .
